I have just had a look at Dave G3YXM's site and pondering trying some 
experiments on 500kHz, so rejoined this group for guidance.

Just put my untuned 110ft longwire into my Datong UC1 upconverter 
feeding my K2 and heard G3AQC working G3KEV. Sounds hopeful! So I am 
contemplating retuning my Butternut HF2V which I have been using on 
160m for the allocation. Probably pretty inefficient (and it 
certainly was when I tried that on 136kHz) but maybe usable. I would 
need to sort something out for the transmit side as the K2 cannot be 
directly used and the idea of a seperate transmitter as I do on 5MHz 
appeals. My old 136 transverter could also be used but I am reluctant 
to mod that as I may have the urge to go down there again sometime 
(though local QRM has kept me away for a while).

I have downloaded the NOV application form and note the guidance 
notes on the spectrum forum site. What is the experience with the NOV 
application process and what choice words should be put on it? As a 
(former) 136 operator and with a current 5MHz NOV I don't expect any 
real problems, and I can continue my quest to operate on impossible 
bands in impossible QTHs and show it can be done...
